AGROALNEXT NH3controlfarm Project: Economical and efficient sensor for ammonia control in livestock farms

Ammonia is a colorless gas with a characteristic pungent odor that can be found in varying concentrations on poultry farms as a result of the volatilization of excrement. Above 20 ppmv (parts per million), it has a negative impact on the health of birds, affecting their growth rate, immune system, and intestinal histomorphology. Furthermore, its release into the environment is known to cause acid rain, acting as a catalyst. Therefore, controlling ammonia concentration on farms is of great importance from a health, environmental, and economic perspective. Current techniques for measuring atmospheric ammonia on farms are either complex and expensive, or inexpensive but insufficient. This project aims to address this through NH3ControlFarm, a passive, colorimetric atmospheric ammonia sensor.
